[Right Triangles Only] SOHCAHTOA[Right Triangles Only] tan∅ = opposite over adjacentStep-by-step explanation:
Step 1: Identify Variables
Angle = 35°
Opposite Leg = 3
Adjacent Leg = x
Step 2: Solve for x
Substitute [tangent]: tan35° = 3/xMultiply x: xtan35° = 3Isolate x: x = 3/tan35°Evaluate: x = 4.28444Round: x ≈ 4.3construct ABCD with AB =5.5cm BC=3.5cm,CD=4cm,AD=5cm, and angle A=45°, with construction steps
Answer:
Step 1: Steps for construction
Take AB at 5.5 cm
Step 2: construct as 45 degree
Step 3: A draw angle ABY=45 degree
Step 4: cut off from AY, a segment AD=5 cm
Step 5: With B as center and radius as 3.5cm draw an arc.
Step 6: With D as the center and mark radius as 5 cm and draw an arc cut the 1st arc at C
Step 7: join B to C and C to D
Result: Then ABCD is a required quadrilateral

Answer:
see the attachment
Step-by-step explanation:
1. Lay out points A and B so they are 5.5 cm apart.
2. Set the compass to 5 cm and draw arcs that intersect above and below segment AB. Label the intersection points Y and Z.
3. Draw segment YZ as a perpendicular bisector of AB.
4. Label the intersection of YZ and AB point E.
5. Using E as the center and AE as the radius, draw an arc that intersects segment YZ at F.
6. Draw segment AD through F. D will lie on the circle of radius 5 cm centered at A. This segment makes 45° angle DAB.
7. Draw an arc of radius 4 cm centered at D through the vicinity of point C.
8. Draw an arc of radius 3.5 cm centered at B through the vicinity of C. The intersection point with the arc of step 7 is point C.
9. Draw quadrilateral ABCD meeting the given requirements.

A car travels 360 miles in 8 hours (with a constant speed). How much time will it take traveling 168 miles?
Answer:
3.7hours
Step-by-step explanation:
Step one:
A car travels 360 miles in 8 hours
the speed is calculated as
speed= distance/time
speed= 360/8
speed= 45mph
Step two:
How much time will it take traveling 168 miles?
having found the speed, which is the rate at which the car is tavelling
time= distance/speed
time= 168/45
time= 3.7hours

Which ordered pairs are solutions to the inequality 3x-4y>5
Note: you did not provide the answer options, so I am, in general, solving this query to solve your concept, which anyways would clear your concept.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the inequality
[tex]3x-4y>5[/tex]
All we need is to find any random value of 'x' and then solve the inequality.
For example, putting x=3
[tex]3\left(3\right)-4y>5[/tex]
[tex]9-4y>5[/tex]
[tex]-4y>-4[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]
[tex]\left(-4y\right)\left(-1\right)<\left(-4\right)\left(-1\right)[/tex]
[tex]4y<4[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}4[/tex]
[tex]\frac{4y}{4}<\frac{4}{4}[/tex]
[tex]y<1[/tex]
So, at x = 3, the calculation shows that the value of y must be less
than 1 i.e. y<1 in order to be the solution.
Let us take the random y value that is less than 1.
As y=0.9 < 1
so putting y=0.9 in the inequality
[tex]3\left(3\right)-4\left(0.9\right)[/tex]
[tex]=9-3.6[/tex]
[tex]=5.4[/tex]
As 5.4 > 5Means at x=3, and y=0.9, the inequality is satisfied.
Thus, (3, 0.9) is one of the many ordered pairs solutions to the inequality 3x-4y>5.

Store A sells 3 t-shirts for $25. Store B sells the same t-shirts: 5 for $40. Which store has the better deal?
Show your work supporting your answer.
Answer:
Store B
Step-by-step explanation:
To figure out which store has the better deal, we need to figure out the price per unit. We can do this by dividing the price by the number of the shirts. Store A sells their t-shirts for 8.33 or 8 1/3 dollars per shirt, while Store B sells their shirts for 8 dollars a shirt. 8 < 8 1/3, therefore Store B has the better deal.
Answer:
B.
Step-by-step explanation:
If you do 3/25=5/x. You would get $41.6. Another way to show it is to divide 25/3 and 40/5, which would give us $8.3 and $8.
If 24 = 118, what is the measure of each of the other
angles?
Answer:
Step-by-step explanation:
Lines l and m are the parallel lines and line n is a transversal intersecting parallel lines.
Since, m∠2 = m∠4 = 118° [Given]
m∠2 = m∠6 = 118° [Corresponding angles]
m∠4 = m∠8 = 118° [Corresponding angles]
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 118° = 62°
m∠1 = m∠5 = 62° [Corresponding angles]
m∠3 = m∠1 = 62° [Corresponding angles]
m∠7 = m∠5 = 62° [Corresponding angles]

√ 25 –2√3 + √27 +2√ 9 Express in simplified radical
Answer:
The expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Step-by-step explanation:
Given the expression
√ 25 –2√3 + √27 +2√ 9
as
√ 25 = 5
√27 = 3√3
2√9 = 6
so the expression becomes
√ 25 –2√3 + √27 +2√ 9
= 5 - 2√3 + 3√3 + 6
= 11 + √3
Thus, the expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
A painter painted about a fifth of a room in a fifth of a day. Coley estimated the painter would paint 6 rooms in 6 days. Is Coley's estimate reasonable? Complete the explanation.
EXPLANATION: Coley's estimate (is not/is) reasonable because the painter's unit rate is (blank) room per day, so in 6 days the painter would paint about (blank) rooms.
Answer:
yes he is correct
Step-by-step explanation:
if he is painting 1/5 of a room in 1/5 of a day he is painting 1 room in 1 day therefore he can paint 6 rooms in 6 days
Janna is looking for an apartment. She plans on paying no more than 25% of her monthly income in rent. If she earns $1,825 a month, which amount represents the most she plans to pay in rent every month?
Answer:
456.25
Step-by-step explanation:
25% as a decimal is .25
To find 25% of her monthly income, multiply 1,825 by .25
1825*.25=$456.25

Find m∠A in ABC if m∠B = 38° and m∠C = 38°
Answer:
∠A = 104
Step-by-step explanation:
Triangles are equal to 180° so if one angle is 38° and the other angel is equal to 38°, then the third angle must make each of those angles add up to 180.
If you add 38 + 38 and subtract the sum from 180 you will get the measurement of angle A
(38 + 38) - 180 = 104
